Answer:
The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions is 18 ounces
Step-by-step explanation:
Given as :
Let The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15%
hydrochloric acid = x ounces
So, Total quantity becomes = ( x + 12 ) ounces
<u>Now, According to question</u>
x × 40% + 12 × 15% = (x + 12) × 30%
Or, x ×
+ 12 ×
= (x + 12) ×
Or, 40 x + 12 × 15 = (x + 12) × 30
Or, 40 x + 180 = 30 x + 360
Or, 40 x - 30 x = 360 - 180
Or, 10 x = 180
∴ x = ![\dfrac{180}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B180%7D%7B10%7D)
i.e x = 18 ounces
So, The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions = x = 18 ounces
Hence, The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions is 18 ounces . Answer
This is the concept of trigonometry, the distance of Lily from the tower will be given by:
tan theta=[opposite]/[adjacent]
opposite=1450 ft
adjacent=x ft
theta=15.7
thus;
1450/x=tan15.7
hence;
x=1450/tan15.7
x=5,158.54 ft
x=5,159 (to the nearest foot)
